GPS Navigation with Laptop

I have a budget USB GPS device which i bought from buy.com for $30 and I'm looking for a mapping software to use with this. I have tried Microsoft Streets and Tips which is nice but it does not recalculate route automatically if you go off track! It's the most ridiculous thing ever and it's the latest version.

I'm going to go across country for the first time and alone from Washington to Indiana. I'd appreciate it if anybody could recommend me with another software that does AUTOMATIC route recalculation.

Thanks!

Nevermind.

I found an third-party add-on while reading Microsoft Forum.

There it is in case anybody comes across the same problem I did.

Nice find! I have now bought myself a TomTom but, if I were to use S&T again I would definately find this addition very helpful.
